Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take place well into one’s 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
At what age does someone become an adult? Many might say that the 18th birthday marks the transition from childhood to adulthood. After all, that’s the age at which people can typically join the military and become fully independent in the eyes of the law.
But in light of research showing our brains develop gradually over the course of several decades, and at different paces among individuals, should we start rethinking how we categorize children and adults?
